What is Cyber Security?

Ever since the world witnessed the internet explosion, the world has grown more and more dependent on the web. Be it day-to-day activities, or the costliest of business deals, be it trivial shopping or the transfer of confidential data – the internet has become the lifeline of all. It is only pertinent then that such an important medium of transfer of data as well as money suffers the undeniable risk of danger.

This danger to internet transactions comes in the form of hacking and other cyber crimes. Cybersecurity is increasingly becoming the need of the hour. The biggest companies and the smallest of start-ups are resorting to cybersecurity measures alike. Not just commercial ventures, cybersecurity is essential for everyone who uses the internet for any purpose. Cyber defence measures are a crucial step for all.

Definition

Cybersecurity refers to a multi-layered protective network that connects multiple devices, programs and data. The intention of cybersecurity is to keep data and transactions safe against cybercrimes. Cybersecurity involved processes and technologies, with the chief aim being guarding devices and data against unauthorized access.

The Cybersecurity process

Cybersecurity follows a layered approach and comprises three components – people, processes and technology. The first and the weakest links are the people of course because employees of a company or the close ones of an individual always pose the maximum threats to cybersecurity. The reasons are many. Often, people are not equipped with ample cyber defences and lack knowledge in the field of cybersecurity measures. They might unknowingly give in to phishing emails and scams.

  1. Essentially, people must be made aware of cyber threats and must be made to understand the necessity and ways of precaution.
  2. They should be taught relevance and usage of passwords, phishing, viruses and antiviruses and so on.
  3. Access management policies can be strengthened so that everyone does not have access to everything.

The second layer, following the human factor, must be the processes followed. There might be situations in the event of which some action would need to be taken for the purpose of cyber safety. Be it a commercial enterprise or a personal account, a good incident response plan is extremely essential, along with a backup. This increases the chances of data recovery in case of any type of hacking or damage to data. Quite often, it is in response to a particular event or occurrence that IT companies revert to a certain protocol. If the processes – including incident response strategies – are in place, the actions would require lesser time and energy.

Also, the prioritization of assets is an important process for anyone who wishes to monitor the important and danger-inviting zones of a network. The harmful consequences can thus be minimized if the company knows where the target is hot.

The Cybersecurity process also encompasses technological prowess. There is no dearth of the number and types of technologies available today before companies and individuals to strengthen their grasp over the cyber defence. One of the most useful technologies for the purpose could be deception strategies, which the company can use to bewilder a cyber-attacker. The dynamic strategies make it difficult for the hacker to differentiate between real and counterfeit assets. Besides, the technology of segmentation can be deployed for strengthening security over multiple layers of assets and data, instead of securing them as a whole.

Why is Cyber Security important?

The importance of cybersecurity lies in the fact that loss of data can turn out to be very expensive for companies and individuals alike. The risk of financial as well as reputational damage is something neither a company nor an individual would like to afford.

Besides, no company or internet user is safe these days. Attackers have developed several means to take the world by storm, and anyone would be next. In such a scenario, the wisest thing to do is to implement cybersecurity measures for safety and precaution.

It is not even like these attackers are alone. Quite often they function as companies themselves and are funded by top millionaires for selfish motives. The financial backing and the nurtured team efforts drive them towards achieving the most impossible of feats. Movies have often shown a glimpse of talented cybercriminals, and that is only a chunk of what they can do.

Cybersecurity risks

There are, no doubt, multiple risks associated with cybersecurity. These risks keep evolving and changing over time, making it difficult to ascertain a particular or permanent solution for all problems at once. In fact, cyber crimes and attacks advance and develop even more rapidly than do the technologies to keep them at bay. The same can be said about the number of hackers to the number of cybersecurity officials or expert’s ratio. Some of the important risks are:

  1. Data security
  2. Database security
  3. Network security
  4. Application security
  5. Business continuity
  6. End-user education
  7. Endpoint security
  8. Cloud security
  9. Mobile security
  10. Infrastructure security
  11. Disaster recovery

How to learn cyber security?

With the number of online platforms teaching all kinds of tactics and skills, learning cybersecurity is no big deal. Very obviously, the first step towards learning cybersecurity would be to understand the term itself and the various related nomenclature. After this, one can take a simple course from any of the popular sites available for an overview of the world of cybersecurity and some basic nitty-gritty.

After one has gained a brief idea of the functions and processes, the components and factors, one can proceed to learn the finer details. This would include the following:

  1. Cryptography
  2. Binary exploitation
  3. Reverse engineering
  4. Forensics
  5. Web exploitation

One can try to understand the terms first using any helpful site that aids in the process of learning cybersecurity. Later, one can proceed to learn these in detail by enrolling onto a course, either offline or online, based on his comfort and preference. One must even try to think like the hacker at this point in time. For this purpose, he must try to involve himself with some hacking trials and games. Software platforms these days allow people to practice hacking legally. Combining online courses and materials with offline conversations and experiences, along with the practice of coding and hacking can give one a fair knowledge of the world of cybersecurity.

In a world that is being constantly driven toward the dark abyss of cybercrimes and social engineering, cybersecurity has become a mandatory tool for companies and individuals alike. With a basic knowledge of the internet, one can equip himself or his business to tackle the adversities of cybercrimes. However, to really be able to refrain from the worst and hard-hitting impacts of the attacks, one must attempt at equipping himself or herself with the most refined and detailed knowledge of cybersecurity as possible.
